Question

Okay, so I was walking down the street today in my mask and this random guy comes up to me.

Man: Hi
Me: Um, hi?
Man: Can I borrow your wallet
Me: sure, why not
Man: Gee, thanks

Then he runs off! How does he plan on bringing my wallet back? It's not like he can read my mind and know where I live. Maybe he reads my blog. I'm still confused why he would need to borrow the whole wallet. I mean, can't I just let him borrow a few bucks? Should I be concerned?
Who is Bob Barker? Does anyone know him? Why won't my car start? Do all cars you get for free from your parents make a muffled choking sound when you start them? Bye.
